I would like a program to take photographies (and if possible video too) where all the parameters, focus, exposure, sensitivity, white balance etc are controlled manually (ideally with widgets on the screen, things like sliders, circular controls (you change the values with the swirly gesture over it) etc, each with it's own text field for typing exact values, if possible, include a B mode (where you keep the exposure going for an arbitrary amount of time), also, if poossible, make it work with the tags stuff and geotagging.
